dtInstances.getLast or getList

[f0def]

Hi
For what these two lines?

    function register(dtInstance, result) {
        //...some code before
        //new promise
        _deferDTInstances = $q.defer();
        _deferLastDTInstance = $q.defer();

        //THIS 2 LINES:
        _deferDTInstances.resolve(_instances);
        _deferLastDTInstance.resolve(_lastDTInstance);

        return dtInstance;
    }

this lines cause a bug

    function getLast() {
        var defer = $q.defer();
        _deferLastDTInstance.promise.then(function(lastInstance) {
            //NOT CALLED
            defer.resolve(lastInstance);
        });
        return defer.promise;
    }

because defer.resolve(lastInstance); not called after navigate in SPA
This leads to that the user handler not invoked, ex:

    DTInstances.getLast().then(function (dtInstance) {
      $scope.dtInstance = dtInstance;
    });

It was to solved in this issue.
Unfortunately, I do not reproduce your issue. The promise in my case is always resolved. Can you provide a plunker or something alike that reproduce your issue?

@l-lin thanks for the answer
I have prepared an example, see here. Steps to reproduce inside the example.
